I am a 5-7 handicap and up until 2 years ago I hit my 7 iron 160-165. After a neck injury I lost 10-15 yards off all my irons. I purchased a set of the ap2 irons and I still haven't gained my distance back. Ive been told that graphite shafts would may help me gain some of my distance back. I wanted to get some advice on what shaft to get. I typically use standard stiff in all my woods and hybrids. I am 44 years old and have an average swing speed. Please let me know if you have any advice for me.
